A cutter carriage for moving a rotary cutter between a front side of the back roller and a back side of the back roller. The preferred system has a pair of guide rods located on the left and right side plates of the sheeting head. The rotary cutter is held at either end by pivot arms. Each arm, in turn is attached to a carriage side piece that slidingly engages one of the guide rods. The two side pieces are joined into a single cutter carriage by an elongate member parallel to the rotary cutter. Each carriage is equipped with a cutter engagement system that moves the pivot arms and attached rotary cutter into an operational position in relation to the sheeting head. When the rotary cutter is serviced, the engagement system is released allowing the pivot arm to move the rotary cutter away from the sheeting head roller, and the cutter carriage is slid along the guide rods making the rotary cutter readily accessible from the rear side of the sheeting head.

The mechanism of claim 3 wherein said mold support comprises a pair of longitudinally spaced arms. 5. The mechanism of claim 3 wherein a vertically extending screw and nut assembly for moving said elevator carriage upwardly and downwardly connects said elevator carriage with a motor carried on one of said guide frame and said elevator carriage. 6. The mechanism of claim 3 wherein said cross carriage carries a motor connected to drive said cross carriage wheels and said transfer carriage carries a motor connected to drive said transfer carriage wheels. 7. The mechanism of claim 3 wherein a pair of transversely extending tracks project from said frame to extend toward said molding machine to support said cross carriage for to and fro travel thereon and wherein said mold deposit location includes a pair of longitudinally adjacent racks positioned adjacent said longitudinally extending tracks having vertically spaced mold support members extending perpendicularly to said longitudinally extending tracks, and pairs of transversely extending tracks at each rack, at the level of said tracks extending toward said molding machine, to support said cross carriage for travel to and from said mold support members of said racks. 8. The mechanism of claim 7 wherein said tracks extending toward said molding machine and said tracks extending toward said racks are mounted in parallelism by said frame. 9. The mechanism of claim 3 wherein one of said elevator carriage and elevator guide frame mounts guide rollers in vertically spaced relation. 10. The mechanism of claim 8 wherein a housing depends from said transfer carriage and supports said cross carriage tracks and said cross carriage. 11. A concrete product mold removal and replacement mechanism in combination with a concrete product molding machine having a mold with at least one vertical through cavity supported on mold supports, a pallet receiver movable vertically for lifting a pallet to close the bottom of said mold cavity, and a stripper head assembly which is movable down to remove the molded product from said cavity conjunctively with downward movement of the pallet receiver and including: a. a frame and a transfer carriage movable thereon from a location longitudinally remote from said mold supports on the machine along a pathway leading longitudinally abeam of said mold supports, said pathway being defined by a pair of transversely spaced apart frame supported tracks and said transfer carriage having transversely spaced motor driven wheels riding thereon; b. a cross carriage and elevator assembly carried on said transfer carriage and incorporating a cross carriage carried for movement transversely to facilitate movement to and from said mold supports, and an elevator having a vertically movable member, said transfer carriage mounting a pair of longitudinally spaced transversely extending tracks and said cross carriage having longitudinally spaced wheels riding thereon; and said elevator comprising a vertically extending guide frame fixed to said cross carriage to depend therefrom and an elevator carriage with a pair of longitudinally spaced arms movable upwardly and downwardly on said guide frame ; and c. motor mechanism for moving said cross carriage transversely inwardly and raising said elevator member to remove a mold carried on said mold supports, returning said cross carriage transversely and moving said transfer carriage longitudinally outwardly; returning said transfer carriage after the mold is replaced, longitudinally toward said mold supports to a position abeam of them; and moving said cross carriage transversely inwardly and lowering said elevator member to deposit a replacement mold on said mold supports. 12. The mechanism of claim 11 wherein a pair of transversely extending tracks project from said frame to extend toward said molding machine to supp
